Abstract

The invention provides a prefabricated box girder centering and anti-rollover control device and a prefabricated box girder erection method. The outside of the ferrule; and two support assemblies oppositely arranged, the two support assemblies are respectively installed on the support member in an adjustable position, and the prefabricated box girder is formed between the two support assemblies and the support member. An embedded positioning groove, the center axis of the positioning groove is aligned with the center line of the support. The invention solves the problems that the conventional control method relies on the naked eye observation of construction personnel when erecting the prefabricated box girder, has low efficiency and has potential safety hazards.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a prefabricated box girder centering and rollover prevention control device and a prefabricated box girder erection method. Background technique [0002] When the prefabricated box girder is erected, according to the requirements of the technical specifications, the center line of the prefabricated box girder must be aligned with the center of the support. Generally, the erection of the prefabricated box girder uses large machinery, and it is difficult to quickly control the displacement error of the millimeter level. within the allowable range of error. [0003] A common control method is to draw their respective center lines in advance on the bridge supports, the ends and the bottom of the prefabricated box girder, and the workers observe and adjust them in time with the naked eye when erecting the girders until the center line of the prefabricated box girder and ...
